Question

Satellite transfer(Hohmann) if r1=230km and r2=400km.Find the delta 1 and delta​

Answer 1

Answer:

Explanation:

Given:  q = 30 kg/s

          Ve = 3,100 m/s

          Ae = 0.7 m2

          Pe = 5 kPa = 5,000 N/m2

          Pa = 0

   

  Equation (1.6),

     F = q × Ve + (Pe - Pa) × Ae

     F = 30 × 3,100 + (5,000 - 0) × 0.7

     F = 96,500 N
